Northrop Grumman Space Systems is looking for a Sr. Principal Optical Subsystem I&T Engineer to support the Electro-Optics (EO) Group within the Launch Vehicles business unit in Chandler, Arizona.

This is a key lead role in supporting the Seeker Integrated Product Team (IPT). The role will coordinate multi-disciplinary team efforts to integrate and test development/flight hardware, ensuring performance at the subassembly and seeker system level.

Responsibilities include leading the integration and testing of hardware, characterizing and evaluating performance, developing the seeker test suite, maintaining and calibrating optical test equipment, and capturing representative data to support physics-based model development.

The selected candidate should excel in a fast-paced environment with diverse assignments and collaborate effectively across all levels of the organization.

Responsibilities

• Lead multidisciplinary teams in the integration and testing of electro-optical subsystems, ensuring top-tier system performance at the subassembly and seeker system levels.
• Develop, author, and review comprehensive test plans, procedures, and test cases based on detailed system requirements and design specifications.
• Oversee the integration of hardware, software, and firmware, ensuring interoperability and adherence to project timelines and technical objectives.
• Execute and troubleshoot complex test procedures, analyze data, and verify that systems and components meet or exceed performance and design requirements.
• Mentor and guide junior engineers; facilitate team training and technical growth.
• Champion root cause analysis and corrective action processes, driving continuous improvement, reliability, and quality.
• Prepare, review, and present detailed test reports, summarizing observations, test configurations, and key results for program stakeholders.
• Maintain and calibrate optical test equipment and environments, ensuring readiness and accuracy for all test activities.
• Collaborate closely with systems engineers, design teams, and program management to ensure alignment of testing strategy with program milestones and customer expectations.
• Ensure all testing activities comply with organizational, safety, and government standards.
• Drive continuous technical learning, staying up to date on emerging optical engineering best practices, tools, and methodologies.

Basic Qualifications

• Bachelor’s degree in Optical Engineering, Physics, Electrical Engineering, Mechanical Engineering, or related discipline from an accredited university and 8 years of relevant experience; or a Master’s degree and 6 years of experience; or a PhD and 4 years of experience.
• Active U.S. Government DoD Secret security clearance at the time of application.
• Demonstrated experience with EO imaging systems (visible to LWIR), including optical design, alignment, and test.
• Proven experience in maintaining and calibrating optical test equipment to ensure measurement accuracy and reliability in integration and test environments
• Proficiency with free-space alignment tools (autocollimators, theodolites, laser systems, FTIR) and hands-on integration of complex hardware.
• Familiarity with the development of custom optical test equipment and developing pathfinder procedures for the use of the equipment
• Managing and maintaining optical laboratory spaces, including oversight of equipment, inventory, and safety protocols.
• Skilled at implementing and enforcing laboratory best practices to maintain high standards of cleanliness and operational efficiency.
